WARNING
Suitable cables for temperatures in excess of 70 °C
If the cable or conduit entry point exceeds 70°C or the branching point of conductors
exceeds 80°C, special precautions must be taken. If the device is operated at ambient
temperatures above 50°C, the permitted temperature range of the selected cable must be
suitable for the temperatures actually measured.
WARNING
Protection against transient voltage surges
Provisions shall be made to prevent the rated voltage from being exceeded by transient
voltage surges of more than 40%. This criterion is fulfilled, if supplies are derived from
SELV (Safety Extra-Low Voltage) only.
